That's right, I meant to ask you about this last time you mentioned this.

Now that you are aware that this is a problem, what do you intend to do 
about it?  Jeff is saying that this may not be fixed until at least v7, 
so waiting for a compiler fix may take a while.

Will you be updating your source?

Are you just finding these with grep, or have you tried the 
-Wonly-top-basic-asm patch?

Fortunately, these aren't a problem for memory or register clobbers.
